are some details of my "hot rod" Dawes Kingpin conversion.
1976 I bought my wife a Dawes "Kingpin" shopper, complete with all
the go faster goodies -including rear rack and shopping bag, handlebar
shopping basket, mudguards, chain guard, lamp brackets and kick
stand. Since arriving in Canada in 1977, it had been languishing
indoors, largely uncared for, unridden and unloved; a wasteful situation
which I found increasingly irksome.
2000, I updated my 13-year-old Bianchi road racer, with a new 9-speed
Campagnolo Veloce group. (See Current
Classics Gallery #113). At its completion, I was left with a
cardboard box full of redundant Campy Victory components, all in
excellent condition, which seemed to be destined to keep the Kingpin
to some Internet exploring of folders, in particular Raleigh "Twenties"
(the other classic folder/shopper of the period), the idea of combining
the two was spawned. The idea of a 6 speed, Campy-equipped, stripped
down, customized, Bike Friday lookalike, hot rod was sufficiently
appealing to warrant the conversion.
The basic Dawes Shopper seems to have a slightly higher build standard
than the Raleigh "Twenty" including "through the frame" cable runs.
following is the component list and sources of the original conversion:

Weight Complete with pump, kickstand and toolbag 24lb* * Getting
rid of the original "heavy iron" has resulted in a saving of at
least 10lb over the original -amazing! Initially I intended it to
be a fun "hot rod" for local riding, but have never ceased to be
amazed at how well it performs. In 2005 I rode it on several club
rides and decided to see if it could be refined a little and turned
into a no compromise day tourer. I have therefore incorporated the
following changes to the original.
attached photos show the latest standard.
combined 2nd bottle holder clamp incorporating a pump.
A softer Bontrager saddle plus a good Topeak tool bag.
A longer Kalloy seat post enabling me to optimise saddle height.
I initially fitted drop bars but found the stem too short, uncomfortable
and to adversely affect low speed handling.
1991 era Profile time trial/triathlon bars were fitted to the existing
"bullhorn" bars in lieu of drops. These give great benefit in headwind
conditions but with hands away from the brakes, renders them unsuitable
for use when riding in a group.
Syncro gear shifter repositioned on the forward end of the Profile
bars to permit shifts to be made when using them.
The biggest change has been to install a Pantour suspension hub
into the front wheel. This is likely to give the biggest improvement
as the small 20" wheels can give a harsh ride on less than perfect
road surfaces. Even though the total suspension travel is barely
1/2", I have been very impressed by the improvement in ride quality.
There is virtually no weight penalty and the low unsprung weight
results in very rapid response to even to the slightest road imperfections
at speed. This was a bit of a bonus and has resulted in improved
performance in all road conditions. The perforated aluminum bracket
outboard of the chainwheel is a chain retainer. The results of all
this have been extremely encouraging.
